In bug 1180706 I turned on touch events for windows nightly builds. This bug is to let it ride the trains. There will be some UX tweaking needed, as well as compat testing to make sure websites that feature-detect touch events don't suddenly start misbehaving on windows touch devices.

This could be first enabled in Developer Edition as well so that webdevs will be able to test their sites easier without having to toggle the pref. I'll post the site compatibility document at some point. # Why Mozilla doesn't have any consistent policy on experimental features? Some features are available both in Nightly and DevEdition, some are only in Nightly, some are disabled by default. That really sucks.

Marking this as a feature to help QA/relman keep track of upcoming work. kats are we still planning to ship apz with e10s in 48? Should/can we prevent that for touchscreen devices? I just noticed a bug that blocks this feature shipping, and this bug is marked as blocking apz for desktop.
We are still planning to ship APZ with e10s in 48, yes. Touch support on Windows will not ship in 48, it is still being worked on. This bug is marked as blocking bug 1013364 ("apz-desktop") but that's a very general meta bug for all desktop apz-related things. The 48 blockers list is hanging off bug 1254668 (and is empty).
Thanks, that clarifies things! I'll keep it in mind for the other bugs that come up.

This is getting close to done. Once all the things that are currently inflight land I'd be happy to flip the switch and let this ride the trains. There are still some outstanding bugs blocking this one but I don't consider any of those ship-blockers and at least some of them can be worked on further and uplifted before this goes to release. Unfortunately the accessibility rewrite is still ongoing and so e10s is still not yet enabled by default on touch devices so we're still not getting a lot of users exercising this code.

I've added a note into all appropriate pages under the touch events docs to make the change clear (see https://developer.mozilla.org/en-US/docs/Web/API/Touch_events). I've also added a note to the Firefox 52 release notes to cover it: https://developer.mozilla.org/en-US/Firefox/Releases/52#DOM_HTML_DOM Please let me know if this description works for you. Thanks!

That works, thanks!
ff version 53.0a2 (2017-02-08) When I installed 53 version touch events were working. But till yesterday | today update. Now again they are not firing up (
Can you check in about:support to see what it says for "Multiprocess Windows" and for "Asynchronous Pan/Zoom"?
Multiprocess Windows 0/1 (Disabled by accessibility tools) Asynchronous Pan/Zoom none
Touch events are only available if e10s and APZ are on. For you it seems that they are off, because of accessibility tools. I know that the e10s team is still working on hammering out the accessibility problems. For now you can force-enable e10s by adding a pref browser.tabs.remote.force-enable in about:config and setting it to true.
> For now you can force-enable e10s by adding a pref browser.tabs.remote.force-enable in about:config and setting it to true. Following your instructions yeah - they're again firing up. Thanks! its strange, i didn't opt anything in these days. Updates were auto when starting-up ff. And suddenly it turned that features off?
As far as I can tell, css touch-action is now enabled (see #8) even when electrolysis is disabled. (Test: http://tests.caniuse.com/?feat=css-touch-action with google translator for firefox addon.) Could this please be mentioned in the release notes?

Ah, you are talking about this: https://developer.mozilla.org/en-US/docs/Web/CSS/touch-action ? I've looked into this, and it looks like work is still ongoing, see these bugs: https://bugzilla.mozilla.org/show_bug.cgi?id=960316 https://bugzilla.mozilla.org/show_bug.cgi?id=1285685

Touch-action is defined in the pointer events specification but it's a distinct property with applicability to touch events, most notably the touch-action:manipulation trick for bypassing the 300ms click delay. (In fact even Safari supports this, Firefox is the last.) The actual implementation bug (bug 795567) is long resolved and the meta bug states that touch-action may be shipped before pointer events. bug 1285685 is the bug for implementing the new values added to the touch-action property in the pointer events level 2 draft spec. In my opinion that shouldn't be a blocker for announcing level 1 support, the current W3C recommendation. I also point to the intent to ship touch-action (all platforms) that references this bug as the enabler: https://groups.google.com/forum/#!topic/mozilla.dev.platform/6CGjsm1XpD4 Some of these arguments are also stated in the intent to enable touch-action on nightly for FF50: https://groups.google.com/forum/#!topic/mozilla.dev.platform/SYEzvXJKw9M Perhaps kats disagrees but it seems like an oversight to me...
Luke is correct. We should probably add touch-action to the dev notes for 52.
(In reply to Kartikaya Gupta (email:firstname.lastname@example.org) from comment #25) > Luke is correct. We should probably add touch-action to the dev notes for 52. OK, cool. Thanks to Luke for the detailed explanation that made sense of it all, and to kats for chiming in ;-) I have added a note to the release notes under CSS/New features: https://developer.mozilla.org/en-US/Firefox/Releases/52#New_features I have pointed to the intent to ship mails fthe full story, rather than to specific bug(s), as I think it makes more sense if you read those.
LGTM, thanks Chris!
This doesn't seem to work on Windows Firefox 52. Setting touch-action:none on the body tag in our css. We are still seeing browser zoom using touch pinch-zoom, and all touch actions seem to still apply. The default Firefox touch actions are all fine except the browser zoom. Firefox doesn't do swipe back/forward actions like Chrome which is good for our web application where we need app pinch-zoom and panning.
Also we set meta viewport initial-scale=1 max-scale=1 user-scalable=no, but Firefox never seems to honor that. Must be a mobile only setting, but would be nice if the desktop honored that as well.

Can you check what it says for "Asynchronous Pan/Zoom" in the graphics section on about:support? Also, if you can post a test page that reproduces the problem for you that would be great. Thanks!

The zoom on desktop isn't the same as the zoom on mobile (at least in Firefox). Mobile has "continuous zoom" where everything on the page is scaled, but desktop only has text zoom or page zoom, which involves reflowing the content. The different semantics mean that the meta-viewport tag doesn't exactly map to desktop zoom.
I am seeing the same problem (touch-action: none; not being honored on Windows Firefox 52). If I remember correctly I tested it on Nightly 52 a while back, where this seemed to work. Under "Asynchronous Pan/Zoom" it says "none" / "nothing" for me (freely translated from German "nichts"). Example page showing the problem: http://output.jsbin.com/hubulobovo
(In reply to Adrian from comment #31) > Under "Asynchronous Pan/Zoom" it says "none" / "nothing" for me (freely > translated from German "nichts"). This means APZ is off, which is probably because e10s is off as well (check what it says under Multiprocess Windows in about:support). Without APZ we don't support touch events and therefore touch-action will not work either.
Yes, it says: 0/1 (Disabled by accessibility tools) What would be the reason for this to happen, and can I somehow work around this?
This is most likely because the touchscreen gets detected as an accessibility device and enables some of the accessibility codepaths, disabling e10s. This was fixed in Firefox 52 for 32-bit builds, but is still a problem for 64-bit builds. It should be fixed in Firefox 53.

The Samsung Notebook 9 Pro with high-precision touchpad reports Async Pan-Zoom as none on both 32-bit and 64-bit. 32-bit FF honors touch-action:none and does not perform browser-zoom/double-tap-zoom/swipe from the touchpad (not touchscreen), whereas 64-bit does do all those things (ignoring touch-action). These are both FF 52, so hopefully 53 works. Edge still doesn't honor touch-action either, and Microsoft created the spec. Only Chrome works right now. This is the fiddle that I modified from elsewhere to test touch-action support https://jsfiddle.net/vd4yr00L/8

I just successfully tested `touch-action: none;` preventing browser default pinch-to-zoom with the following snippet in Edge and IE11: http://output.jsbin.com/hubulobovo
Sorry wrong thread, but Edge is bust with your example. I still get browser-zoom in Edge on the Samsung, and with my fiddle. I'm just setting touch-action:none on the body of the fiddle.

I'm just setting > touch-action:none on the body of the fiddle. Oh that's interesting. I've been testing it using the touch screen on my Dell Precision M3800 laptop, whereas you have been using your touchpad. Testing it using my laptop's touchpad I get the same results as you. For completeness sake the browser version used is: Microsoft Edge 38.14393.0.0, Microsoft EdgeHTML 14.14393.
Most touchpads are not going to be treated as touch devices. Touchpad drivers might have their own gesture detection code and deliver gesture events to the browser/OS, so in those cases touch-action will not apply to that input. Only if the touchpad is delivering WM_TOUCH messages to the browser will touch-action apply. Touchscreens generally produce WM_TOUCH.
Okay, I checked and the Razer Stealth does not have a high precision touchpad, and the Samsung Notebook 9 Pro does. That still does't explain the magnitude differences in reported numbers on wheel event deltaXY in Firefox. Pinch, for example, sends a huge value on Samsung, and tiny value on Razer. I'm not sure how people can respond to this much variation in data. These are both running Windows 10, and are less than a year old. It's not going to help if touch/gesture convert their own values into these same deltas. // On Firefox, on Razer, we can only do this conversion for pans, zoom and pinch-zoom are // not scaled by dpr or numLinesToScroll, but the last zoom event is scaled by numLinesToScroll (big spike). // This happens when the inertia slows on the Razer. Also seeing 4, 8, 4, 8 at tail end of inertia. // And there are large inertia spikes on Chrome Windows, and cutoff at the tail of inertial movement. // Razer, the base units for delta using touchpad are: // pan = 0.2 no dpr, 6x bigger than zoom/pinch // pan-w = 3.0 this is 15x bigger than touchpad // zoom = 0.01666 no dpr, but numLinesToScroll spike at end of pinch (can be 1.666 or higher) // zoom-w = 3.0 this is 80x bigger than touchpad 180/60/1 if normalizing on 0.016666 // pinch = 0.01666 no dpr, but numLinesToScroll spike at end of pinch // these magniutes overlap, making it difficult to detect pinch or actual wheel use // may need to identify from key_down // Samsung // pan = 0.075 <- differences // pan-w = 3.0 // zoom = 0.075 <- // zoom-w = 3.0 // pinch = 3.0 <-
So this is way off-topic for this bug now, since it has nothing to do with touch-action. Please direct any follow-ups to this on a new bug if you are having trouble with wheel events. That being said, most likely you need to take the deltaMode into account to normalize the deltaX/deltaY values. https://developer.mozilla.org/en-US/docs/Web/API/WheelEvent/deltaMode
Not trying to take things off-topic, but trying to share the results I have. The differences are more significant than a missing multiplier for deltaMode. Also the last value on zoom and pinch-zoom uses numLinesToScroll causing a massive spike at the end. Just pointing to larger problems with event handling in Firefox. Chrome and Edge have their own problems too.
Pointer events are supposed to encompass touch-pad, and touch-action seems to encompass the gestures that the touchpad is defaulting to that are nearly identical to the touchscreen gestures on the same Samsung device. Indeed Microsoft states that touch-action doesn't affect mouse, keyboard, or touchpad. I'm assuming there then has to be some identical set of filtering to disable the touchpad, or a lot of event.preventDefault() calls.
